How to improve FPS in 7 Days to Die (PC)
7 Days to Die has spent years in Early Access and remains a particular beast when it comes to running well. Its fully destructible voxel terrain forces the engine to recalculate meshes and physics every time you dig, build, or blow something up, which makes the CPU the game's real bottleneck. The GPU paints the scene, but it's your processor's single-thread performance that decides whether your base holds up during Horde Night without turning into a slideshow. Here we'll squeeze out the settings that really matter: render distance, chunk generation, and the zombie load of full-moon blood nights.

Calculations based on our FPS model combined with the % gain of each setting (measured in public benchmarks).
1. Quick wins (no visual loss)
Start here. Each one adds a little, but together they give +70% free FPS.
View Distance / Chunk Reset Distance
This is the single most CPU-hungry variable in the whole game: every visible chunk is voxel geometry that has to be generated, lit, and kept in memory. Dropping it from high values (10-12) to 6-7 frees up a huge amount of CPU cycles without your base looking any worse. During night hordes it's literally the difference between a stable 60 FPS and constant stuttering.
Shadow Quality
Dynamic shadows on destructible terrain are expensive because the engine has to recalculate the shadow map every time the world changes shape. Dropping to Low eliminates much of that ongoing recalculation without the game losing its already fairly rough visual identity.
Grass/Foliage Density
Vegetation in 7 Days to Die renders as thousands of individual instances spread across the biome, and this spikes hard with high view distance. Reducing its density frees up both CPU (culling) and GPU (draw calls), and also improves visibility of zombies approaching through the grass.
Reflections
Reflections on water and metallic surfaces add an extra render pass that's rarely appreciated in a game with this aesthetic. Disabling them is an almost free FPS gain, especially in biomes with large rivers or lakes.
Occlusion Culling / Dynamic Mesh
Keeping occlusion culling enabled prevents Unity from trying to render voxel geometry hidden behind other blocks or inside caves, something especially relevant in heavily fortified bases with multiple layers of modified terrain. Disabling it by mistake is usually the cause of inexplicable FPS drops inside enclosed structures.
2. Medium impact settings
Here's where most of the FPS is. Minor visual impact, major performance impact.
Terrain Quality
Controls the resolution of voxel textures and the level of detail in transitions between terrain blocks. On Medium the terrain is still perfectly readable while reducing texture streaming load during exploration and mining.
Texture Quality
Mostly affects VRAM usage more than raw framerate, but on cards with limited memory, lowering this setting avoids microstutters from streaming when entering new areas of the map. On GPUs with 6GB or less it's a recommended preventive setting.
Particle Quality
Explosions, mining dust, and blood effects generate a lot of simultaneous particles, especially during fights with several zombies. Lowering this option reduces occasional FPS spikes at the most chaotic moments, which usually coincide exactly with Horde Night.
Anti-Aliasing
Heavier AA options barely justify their cost in a game with this voxel aesthetic and relatively low detail resolution. FXAA smooths edges enough without noticeably penalizing framerate.
V-Sync
V-Sync adds input lag and can introduce microstutters when framerate fluctuates from chunk generation, something that happens constantly in this game. It's preferable to disable it and use an FPS cap or G-Sync/FreeSync if your monitor supports it.
3. Upscaling (DLSS / FSR / XeSS)
The biggest gain in the game. Compatible with almost any modern GPU.
4. Tips by GPU
NVIDIA
- •Enable the "Prefer Maximum Performance" mode in the NVIDIA control panel to prevent the card from downclocking during chunk-generation pauses.
- •Force Low Latency Mode to "Ultra" to reduce accumulated input lag, especially noticeable in melee combat during Horde Night.
- •Keep drivers updated: 7 Days to Die ships frequent Early Access patches and shader cache profiles sometimes need to regenerate after each major update.
AMD
- •Enable Radeon Anti-Lag to offset the typical microstutters from voxel terrain regeneration.
- •Use Radeon Chill with a moderate range (say 45-90) to avoid temperature spikes during long intensive mining sessions.
- •Check that the power mode is set to "Performance" in the Adrenalin software, since the game is prone to inconsistent performance in power-saving modes.
Sistema
- •Install the game on an SSD (preferably NVMe): chunk generation and loading depend heavily on disk read speed, more so than in most games.
- •Close background processes and browsers: since it's a single-thread-dominant game on CPU, any process using an active core can cause noticeable FPS drops.
- •If you play on a dedicated or rented server, check that it has enough CPU assigned, since zombie and terrain simulation runs server-side and can limit your FPS even if your own PC is powerful.
5. Known game issues
FPS drops when generating new chunks
When exploring unvisited areas or after teleporting, the game can briefly freeze while generating the voxel terrain of surrounding chunks. Reducing View Distance and using a fast SSD noticeably mitigates the problem, though it doesn't eliminate it entirely on large maps.
Performance drop during Horde Night with many zombies
When dozens of zombies calculate simultaneous paths toward the base through modified terrain, the server CPU (or your own PC in local games) can become completely saturated. Simplifying base traps and reducing the zombie count in the world options helps keep FPS stable.
Progressive memory leak in long sessions
Sessions of several hours in a row, especially in heavily explored and modified worlds, can accumulate RAM usage until it causes stutters or crashes. Periodically restarting the game during marathon sessions is the community's recommended solution while The Fun Pimps continues optimizing memory management.
Estado: Partially mitigated in build A21+, pending a definitive fix
